I think this is something that could be added in another update, and I also think it would be nice to somehow designate plays to call on the goal line. You can sort of get the goal line play called if you set Short situations inside your Opp 5, but that eats the Inside Opp X settings for other non-goal line situations. You can also set a 4-4 to have all the LBs at the line and you can get 8 men in the box and set the play to always blitz to get 9 in the box, but that's not exactly the same as having a goal line defense.
